Common Questions About the Coway Airmega AP-1512HH Mighty Air Purifier
Should I leave the Vital Ion feature turned on?
We recommend leaving Vital Ion off. While it is CARB-certified compliant, mechanical HEPA filtration is completely sufficient and avoids generating even trace secondary ozone.
How does Eco Mode work on the Coway Mighty?
When the particle sensor detects no pollution for 30 consecutive minutes, the fan automatically powers down to 0 RPM to save electricity. If pollution rises, it restarts instantly.
How much does a year of filters cost for the Coway?
An official Coway 1-year replacement pack (Part #3304899) costs approximately $45–$55 and includes 1 True HEPA filter and 2 deodorizing carbon filters.
